Official deFaced fonts license to use your font any way you see fit besides
reselling it.

Pretty complete character set and permission to ask me to make a character
you need that might be missing.

Peace of mind knowing you did the right thing by paying someone for their
artistic creations and hard work instead of just taking it without giving anything
back.

The latest and most polished version of the font or family, plus any alternate
versions I might have laying around.

Many of the registered versions have kerning pairs and other advanced stuff
that takes a lot of time and work to get right. (The free ones or shareware
versions you got here or somewhere on the web are mostly just the first version
straight from the scanner or tablet and may not even have all the characters
yet.)

An email from me once your payment is approved through PayPal with a zip
file attached containing the fonts you purchased and maybe a surprise.
